Error web_api_show_package

I need to export a policy package from the MGMT R80.10. This policy is applied to a virtual FW on VSX R76 Environment, however when I run "web_api_show_package.sh -g FW_1" it shows me the error "Script stopped running due to severe error!".

I've visited some forums without finding the answer, have you experienced this issue?

We have run "web_api_show_package.sh -g FW-1", however we see the error "failed to get string data", we verify the process API Stopped.
